Royal Style and Titles Act

A Royal Style and Titles Act, or a Royal Titles Act, is an act of parliament passed in the relevant country that defines the formal title for the sovereign as monarch of that country. This practice began in 1876, when the Parliament of the United Kingdom passed the Royal Titles Act. By that law, and the subsequent Royal Titles Act 1901 and Royal and Parliamentary Titles Act 1927, the monarch held one title throughout the British Empire. Following the enactment of the Statute of Westminster 1931, the governments of the now separate and independent realms sharing one person as sovereign agreed in 1949 that each should adopt its own royal style and title, which was done in 1952. As colonies became new realms, they passed their own royal style and titles acts. Most of the laws were created during the reign of Queen Elizabeth II.
